(Cl. 297-443) This inventionrelates to knockdown frames for upholstered type furniture.

It is therefore a primary object of this invention to provide a framefor upholstered furniture which may be readily assembled from pieceswhich may be manufactured with greater ease and thereby also facilitateshipping and storage of the frames in disassembled condition.

Another object of this invention in accordance with the foregoingobject, is toprovide a furniture frame which is formed by the assemblyof component frames fitted together to form an accurate and rigid frameassembly.

In accordance with the foregoing objects, this invention may be appliedto the assembly of an upholstered chair frame formed from a back frame,a seat base frame, two sidearm frames all of which are locked inassembled position by means of four legs which extend throughinterlocking projections on the base seat frame and are secured to thebottoms of the sidearm frames.

These together with other objects and advantages which will becomesubsequently apparent reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming a part hereof, whereinlike numerals refer to like parts throughout, and in which:

FEGURE 7 is a perspective View of a lower rear corner of a sidearmframe.

FEGURE 8 is a top plan view of the base seat frame.

Referring now to the drawing in detail, all of the components whichmake-up an upholstered seat in accordance with the principles of thisinvention are shown in FlGURE 1, wherein reference numeral lit)designates the back of the seat, 12 designates the base seat portion, 14indicates the sidearms while 16 designates each of the egs thereof.

As more clearly seen in FIGURE 4, the frame for the back of theupholstered piece is made-up of a pair of side members it which areinterconnected at the top by a top member 2ft which overlaps the sidemembers 18 by a small amount. The fronts of the side members 13 areinterconnected by a front member 22 below which a recess portion 24 isformed within each of the side members 1% for receiving the base seatportion as will hereafter become apparent. The rear portions of the sidemembers 18 are interconnected by rear bracing member 26. Adjacent thetop portion of the side members "'18 there is disposed upper sidemembers 28 which are spaced from the side members by means of spacingmembers 34) and 32 which form therebetween a space 34 for purposes aswill hereafter be explained. The upper side members 23 are also spacedfrom the side members 18 ice by means of the overlapping portions of thetop member 2%. Also, disposed at the rear bottom portion of the sidemembers 18 are slots 36 as shown dotted in FIG- URE 4.

Referring now to FIGURE 4 again, the sidearm frame assemblies 14 includea top member 33 attached to a pair of vertical front and rear members 40and 42 which are also interconnected by a bottom member 44. The side armframe 14 is further braced by a horizontal brace member 46, the frontface of which is flush with the ront edges of the front and rear members40 and 42. As seen in FiGURE 7 the rear side member 42 of the sidearmframe assembly 14 has connected thereto at a lower end thereof a pin ordowel 48 while: the bottom member 44 has cut therein a pair of recessesor slots 5%) and 52, the pins 48 and recesses 54 and 52 being providedfor purposes as will hereafter become apparent. Also, as seen in FlGURES2, 3, 4 and 5, a pro ection member 54 is connected to the top member 38and the brace member 46 or tile side arm frame 14, said member 54projecting upwardly beyond the top of the top member 33 for purposes aswill become hereafter apparent. Also disposed Within the bottom member44 of the sidearm frames 14 from the top surfaces thereof are nutreceiving recesses 56 as will be more dearly seen in FIGURE 5. The outreceiving recesses are interconnected with the slot portions 5t; and 52by means of holes 58 as will also be more clearly seen in FIGURE 5.

Referring now to FlGURES 5 and 8, the frame for the base seat 12 isformed by a Pair of side members 60 which are interconnected at a rearend by means of a rear member 6L having projecting portions 64 extendinglaterally tnereoeyond while the front portions of the side members 619are interconnected by a member 66 similar to member 6.2 and also havingprojecting portions 68 similar to projecting portions e4. Apertures 70are disposed witmn the pro ecting portions s4 and 68 for purposes aswill hereafter become apparent. Also an intermediate bracing member 72is provided between the side members 6%? and also a from member 74interconnects said side members. As will be apparent from FlGURES 2 and5, the side members 63 of the base seat frame slope downwardly from thefront toward the rear portion thereof for the obvious purpose of forminga rearwardly downwardly sloping top seat portion for the upholsteredchair.

As will be seen in FIGURES 2 and 3, each of the legs 16 which may be ofvarious shapes and sizes or designs, has connected thereto at its top ascrew member 76 which may be threadedly engaged with a nut member 78 aswill be more clearly seen in FIGURE 3.

Referring now to FIGURES 3, 4, 5 and 6, the assembly of the sidearmframes 14 with the back frame ill will become apparent. The sidearmframes 14 have their rear portions assembled against the lower side ofthe side members if) of the back frame 10 and are moved upwardly withrespect thereto so that the pin 43 is aligned within the slot 36 as seenin FiGURE 6, while the projecting member 54 is received Within the space34 formed between the spacing members 3% and 32 as more clearly seen inFEGURES 3 and 5. Accordingly, the side frames 14 are assembled againstthe side members 18 of the back frame it) beneath the exposed upper sidemembers 23, with the interlocking projections 48 and 54 being hiddenwithin the back frame 1% while the use of the two interlockingprojections prevents any angular displacement between the sidearm framesand the back frame. Therefore, the sidearm frames 14 may be assembledwith the back frame ill so as to prevent any horizontal or angulardisassembly therebetween. It will therefore be apparent that in order toassemble the sidearm frames 14 with the back frame, it will be necessaryto merely lower the back frame it} down between the side arm frame withthe slots 36 and 34 being aligned with the projections 48 and 54respectively.

The assembled sidearm and back frames may be assembled with the baseseat frame by lowering over the base seat frame as shown in FIGURE 5wherein the recesses 5'0 and 52 in the bottom members 44; of the sidearmframes 14 are in alignment with the projections 64 and 6'8 of the seatframe while the recess portions 24 of the back frame side members .18are in alignment with the rear top corner portion of the seat frame sothat the seat frame may be assembled with the other components as shownin FIGURE 2. As also shown in FIGURE 3 wherein the sidearm, back andseat frames are assembled, it will be observed that the aperture '70within the projection 64 of the seat frame is in alignment with theaperture 58 within the bottom member 44 of the sidearm frame.Accordingly, as seen in FIGURE 3, the legs 16 may be assembled to thebottom of the projecting portion 64 of the seat frame by insertion ofthe screw member '76 through aperture 7t? and through aperture 53whereby the leg and screw member 76 may be rigidly attached to thebottom member 4 of the sidearm frame 14 by means of the nut member 78being threadedly engaged with screw member 76 and fitting within therecess 5'6. It will therefore be apparent, that the legs are not onlyattached to the seat frame and sidearm frames but also lock the wholeassembly together.

From the foregoing description, assembly of the various components andtheir manufacture will be apparent. It should be appreciated therefore,that the entire frame is tied together by means of the legs in a mostefficient manner and with the requisite rigidity in order to hold theentire frame assembly in assembled position. It will also be noted thatthe back frame 10 can only be disassembled from the sidearm frames 14 byrelative movement thereof in an upward direction which is unlikely forsuch a relatively heavy piece and will overlie the rear portion of theseat frame to give a neat appearance when the upholstered pieces areassembled. Also, when so assembled the back portion M will be incapableof being angularly displaced relative to the seat because of its doubleinterlocking arrangement with the sidearm portions 14. Furthermore, aswas hereinabove explained the sidearm portions 14 will be rigidlyattached to the seat portion by means of the legs. It will be also notedthat all of the interlocking projections are rigid extensions orintegral extensions of the frame forming each of the components so thatthe assembly is more secure.

The foregoing is considered as illustrative only of the principles ofthe invention. Further, since numerous modifications and changes willreadily occur to those skilled in the art, it is not desired to limitthe invention to the exact construction and operation shown anddescribed, and accordingly all suitable modifications and equivalentsmay be resorted to, falling within the scope of the invention asclaimed.

What is claimed as new is as follows:

A knockdown frame assembly for furniture comprising a back frame havingsides against which sidearm frames are assembled, upper exposed sidemembers connected to said back frame sides and spaced therefrom byspacing members forming downwardly opening slots therebetween,downwardly opening slot means formed at bottom ends of said back framesides, vertical projections and pins connected to said side framesreceived within said slots and slot means respectively, a base frameassembled within recess portions of said back frame sides, a pair ofoutwardly extending horizontal projections connected to each end of saidbase frame at its bottom, said latter projections being received withinrecesses formed within bottom members of said sidearm frames and aplurality of legs each having an upwardly extending screw memberattached thereto which extends through one of said horizontalprojections and are threadedly engaged with said bottom members of thesidearm frames.
